Yes - I get them a lot. I get bacterial UTI's. I think it makes me more susceptible. If you don't get bacterial cystitis, what are you dealing with? Usually if its after intercourse it is contamination from e.coli (gross but they are located near each other). Try showering before sex and peeing right after sex. You can also drink lots of water and eat something to make the pH of your urine acidic.
I also get bacterial UTIs but after it clears, I have non bacterial cystitis for a while. Thanks!
